Madcow...Workout A is actually the hardest of the week. It will use the new weight increase for a set of 5 reps, where on the previous Friday you performed only 3 reps with this weight. In addition, your ramping sets will all be slightly heavier than the ramped sets from last Friday's workout.

So Mondays will have more intensity. Fridays have less volume, and less average intensity per rep.
